Dear Technical Support Team,
My schematic is similar to 8.2.6 Typical Differential-Input BTL Application With BD Modulation Filters, DKD Package. The inductor multiplier is the recommended typical value of 10 uH. Everything else is similar. In this case, A short-circuit test was performed between OUT_LEFT_M and OUT_LEFT_P. After power-on, a short-circuit was applied and -10dBm/1kHz was applied.
"7.3.10 PBTL Overload and Short Circuit" describs "and with these high currents, the protection system will limit PBTL speaker overloads, terminal-to-terminal shorts".
Can the protection circuit described above in the datasheet work in my short circuit test? I would like to send you a detailed circuit diagram, so I would like to communicate via private message or email.
Best Regards,
ttd
